Pro Workflow (Step-by-Step)
- Prepare the drum and use pre-mixed material if necessary
- Mount the mixer correctly in the bung hole
- Connect the compressed air system and ensure grounding
- Slowly increase the speed
- Continuously mix and pump the material
- Adjust the direction of rotation if needed
- Clean and depressurize after use
Typical Problems & Solutions
1. Foaming
→ Reduce speed
→ Adjust rotation direction
2. Poor pumping performance
→ Check seals
→ Seal the suction line
3. Irregular operation
→ Check air filter
→ Clean muffler
4. Material drying up
→ Clean immediately after operation
→ Avoid standstills
Maintenance & Care
- Grease the motor regularly (every 3–4 months)
- Inspect air filter and muffler
- Check belts and bearings
- Clean valves (approx. every 2000h)
- Remove material residues immediately
FAQ
How does the mixing technology work?
The material is transported from the bottom of the drum upwards via a helix and distributed evenly.
Can I pump and mix at the same time?
Yes, thanks to the integrated suction function.
Which direction of rotation is better?
Upward movement reduces air intake.
Which media are suitable?
Lacquers, paints, and comparable liquids up to approx. 1000 cP.
How do I avoid damage?
Do not run dry and monitor the pressure.
Conclusion
The Twistork® Helix is a powerful solution for industrial mixing processes. By combining efficient mixing with integrated pumping, you save time, reduce material loss, and increase process reliability.
